About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X700X600SH
The SCT100X700X600SH is a double-acting tandem cylinder that delivers four fixed rod positions—0 mm, 700 mm, 600 mm, and the combined 1300 mm total travel—by pressurising its two piston sections independently. Each 100 mm bore section generates 3927 N of push force at 0.5 MPa, rising to 7068 N at the maximum 0.9 MPa operating pressure, driven through a rigid 25 mm diameter rod. This model is built with high-temperature Viton (FKM) seals, shifting the operating range to 0–150°C for demanding thermal environments.
Both 700 mm and 600 mm section strokes exceed the standard 500 mm limit, making this a made-to-order configuration with a body length A(SCT) of 308 mm plus the extended stroke lengths. A factory-integrated magnet allows direct clamping of CMSG, DMSG, or EMSG sensors to the tie-rod barrel for non-contact position feedback at each stop point. The adjustable air cushion on each section decelerates the piston smoothly, though an external rod lock or pilot-operated check valve must be added if the load needs to be held at any intermediate position without sustained air pressure.

| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 29 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). This configuration exceeds the 500 mm standard section stroke, so it is a non-standard / made-to-order build. Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 700 mm |
| P2 (section 2) | 600 mm |
| P3 (both extended) | 1300 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
Force is per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X700X600SH Is Used
Multi-Stop Material Sorting
Uses the four discrete positions (0, 700, 600, 1300 mm) to divert parts onto three separate conveyor lanes in a high-temperature sorting system.
Two-Depth Hot Press
Provides two distinct pressing depths (600 mm and 1300 mm) plus a retracted position for loading parts in a thermal forming or laminating press operating up to 150°C.
Staged Assembly Transfer
Shifts a workpiece through three assembly stations (700 mm, 600 mm, and full 1300 mm extension) with sensor confirmation at each stop via the built-in magnet.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X700X600SH the Right Cylinder?
Select the SCT100X700X600SH when your process requires four distinct mechanical stops with high thrust across a long travel envelope, avoiding the complexity of two separate cylinders and external hard stops. If your force requirement is lower, stepping down to an 80 mm bore reduces the per-section push to 2513 N at 0.5 MPa, while still supporting long non-standard strokes. For a direct replacement, match the 100 mm bore, both the 700 mm and 600 mm section strokes, PT port thread, basic mounting, and the -S magnet option; substituting a model without the H suffix would downgrade the seal to standard TPU and limit the temperature ceiling to 70°C. Because the individual section strokes exceed 300 mm, evaluate the rod for side-loading and consider adding external guides or a rod support to prevent bending under offset loads.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 700 + 600 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X700X600SH FAQ
It provides four discrete, fixed stop positions. The rod can be positioned at 0 mm (fully retracted), 700 mm (first section extended), 600 mm (second section extended), and 1300 mm (both sections extended). These are not infinitely adjustable; they are mechanically fixed by the two stroke lengths.
Yes, it is a direct replacement for setups using two individual cylinders to achieve two extended stops, provided the strokes match 700 mm and 600 mm. The SCT integrates both strokes into a single tie-rod body, reducing mounting hardware and alignment complexity. Ensure the replacement unit matches the PT port thread, basic mounting, and the -S magnet if sensor feedback is needed.
